Lava Rock is a common name for rocks formed by a volcanic eruption, it is also referred to as Volcanic Rock. When super-heated magma (lava) is released, it rapidly cools off and hardens. This rapid cooling results in the rock becoming highly porous (having holes) and a low density (light weight).

The high porosity (having millions of fine holes) makes Lava Rock a very good Biological Media. Lava Rock is commonly available in two types: the Red Lava Rock and Black Lava Rock. The size can vary from small granules to large stones.

Due to the large number of pores (holes) and some being deep like tunnels, it is speculated that in the deeper pores, anaerobic bacteria develop due the lack of oxygen and that these anaerobic bacteria start Denitrification – the process of removing the Nitrates. This is considered an outstanding benefit of Lava Rock.

Lava Rock, in any size, is absolutely safe to use in Filtration (Biological Media) and Aquascaping.

Commonly, Lava Rock is available in two colours - Red & Black

While there isn't a law requiring ecommerce stores to have a Return Policy, you may need one if you wish to enforce your terms and parameters of returns and refunds.

For example, in the state of New York, if a retailer does not provide a Return & Refund Policy, the retailer will be required to accept returns and give refunds for all merchandise returned within 30 days of purchase. If you wish to limit this in any way, you will need to create and post a Return Policy with your own custom terms.

Another reason for having a Return Policy even if not required by law is that most consumers prefer to shop at retailers with a clearly-posted Return Policy. This is especially important when shopping online, as more issues are likely when purchasing something without being able to see it in person first.

If you don't have a Return Policy, you may be at the mercy of state laws regulating return and refund timeframes. You may also lose potential customers who are concerned about not being able to return a product if they need or want to.
